4 Stepping Stones to Sustainability for New Construction Firms

The construction industry has a well-deserved reputation for being an environmental polluter. It has gotten away with ungreen practices because the other sectors are just as dirty, if not more. However, climate change has made the world less tolerant of environmentally unsound organizations. Governments have joined the sustainability movement, so the writing is on the wall for maladaptive enterprises.

Many firms are slow to adopt greener practices, but the influx of startups can accelerate the sector’s sustainability transformation. New design-build firms, general contracting businesses, and subcontractors are better positioned to embrace eco-friendly initiatives.

The corporate culture is still a blank canvas, so start fresh with these four tips.

Go Digital

Technological adoption and sustainability go hand in hand. Outdated methods and crude tools limit your ability to overcome your blind spots and find opportunities to operate more sustainably. Investing in digital technologies is necessary to address your pain points and streamline your processes.

Which innovations should you prioritize? There are numerous excellent candidates:

Mobile devices and messaging tools can harness cloud computing’s potential to promote remote resource access and foster interconnectedness. The interplay between these technologies will break down the usual communication barriers, making it easy to keep everybody on the same page.
Computer-aided design, building information modeling, and construction management programs streamline processes. They have unique functions but digitize data so you can review information more granularly. Analytics programs can reveal insights to solve problems that harm the environment, like surplus inventory and rework.
LiDAR and camera-equipped drones, wearable Internet of Things devices, and telematics systems can collect data on almost anything. They can help you precisely and accurately scan the landscape to minimize disturbance on existing ecosystems, quantify worker performance to identify and correct wasteful habits and keep tabs on equipment usage.
Bots automate tedious tasks, allowing you to conduct construction work more efficiently. Robotic arm 3D printers and bricklayers can help you complete projects faster and decrease material waste.

Construction has been slow to innovate primarily due to employee hesitance. Feeling intimidated by innovative solutions and receiving inadequate technical support are some of the usual baggage crews carry. Budget for training and continuous learning, as technologically savvy workers feel comfortable with innovations and can maximize their tools to run your business more sustainably.

Be Circular

Circularity promotes using renewable, reclaimed or recycled materials, reusing or repurposing items, recovering salvageable materials, and designing structures with easily recoverable components. Such practices aim to leave the remaining virgin resources untouched because logging, mining and quarrying have considerable environmental consequences. These extraction methods destroy natural habitats, displace wildlife, eradicate biodiversity, pollute soil, water and air, and reduce natural carbon sinks.

Considering the planet’s finite resources, the construction industry has to switch from the linear to the circular model sooner rather than later. Otherwise, the sector will face crippling supply chain disruptions, which can result in project delays and loss of profits. How do you join the circular economy?

Buy reclaimed, recycled and repurposed construction supplies: Try doing so whenever you can to help conserve virgin resources.
Choose vendors carefully: Circular suppliers engaging in unethical practices practice greenwashing, not sustainability. Exercise due diligence to ensure your supply chain partners are as green as they claim to be to avoid enriching environmentally damaging businesses.
Select used equipment over new products: Purchasing pre-owned tools, machines and vehicles is sustainable because they’re already around. Ordering brand-new assets incentivizes manufacturers to build more products, potentially using newly extracted raw materials. Plus, pre-owned models save you money because used items cost less, less downtime is necessary for training and replacement parts are usually cheaper.
Put a premium on prefabrication: Prefab construction minimizes waste since it’s easier to control material usage when building components off-site in a factory-controlled environment. More importantly, construction modules lend themselves to deconstruction, simplifying dismantling and material recovery for reuse or resale.

Emit Less

Decarbonize your operations at every turn. Switching from diesel to electric is one of the best ways to do so. Powering your assets with nothing but electricity eliminates air and noise pollution on-site.

Running on electricity doesn’t automatically translate to fewer greenhouse gas emissions. In 2023, fossil fuels produced 60% of the electricity generated in the United States. The nation’s power mix will be cleaner once green hydrogen becomes ubiquitous, so operating electric construction assets will be even more eco-friendly in the future.

If upgrading to electric equipment doesn’t make sense for you, adopting renewable diesel is the next best thing. This alternative fuel is chemically identical to fossil-derived diesel, so you can use it on your existing assets without modifying anything. Renewable diesel releases fewer climate change gasses because it burns cleaner.

Furthermore, localize your supply chain. Ships are responsible for 3% of all greenhouse gasses linked to human activities globally. Ordering materials from overseas will increase your construction firm’s carbon footprint, but transporting domestically sourced materials involves fewer emissions. It’s also logically simple because they cover less ground and avoid Customs and Border Protection. As a bonus, you enjoy shorter lead times.

Make it a mission to have a lean mindset. A lean construction philosophy aims to cut waste at every chance, minimizing idle time and redundant processes that drive up greenhouse gas emissions.

Look Ahead

Sustainability isn’t an objective — it’s a purpose. It’s a never-ending pursuit, so always seek new ways to run your construction firm in an environmentally friendly way.

Lack of knowledge about emerging technologies is among the limiting factors in innovating. Curiosity is the antidote to ignorance, so keep up with the hottest trends in eco-building. Transparent wood, superabsorbent hydrogel, luminescent cement, 3D-printed soil structures, biodegradable polyurethane foam and plasma rock are some of the most promising innovations.

Most promising eco-friendly construction solutions take a lot of development before becoming ready for sale — and only a few ultimately gain mainstream acceptance. Although many ingenious ideas don’t pan out, be ahead of the curve. Use them to inspire regenerative and climate-resilient building designs that positively impact the environment for decades.

Take Small Steps Toward Sustainability

These four strategies only scratch the surface of what you do to be a force for good in the sector’s sustainability transformation. Strive to be more eco-friendly as you grow and you’ll establish a solid reputation as a green construction business.

Nurturing greener tenants for more sustainable buildings

Posted on March 28, 2022 by dishanth

Switching lights off when they are not in use, turning up the temperature on air-conditioning, and saving water – these may seem like small actions, but they are vital to the fight against climate change.

Today, buildings are responsible for nearly 40 per cent of greenhouse gas emissions, with their construction and operations contributing 11 per cent and 28 per cent respectively. Efforts to improve their sustainability are not going far enough, and buildings remain “off track” to achieve carbon neutrality by 2050 according to a report by the International Energy Agency (IEA) in November.

Managing climate-friendly and energy-efficient buildings is crucial to achieving the Paris Agreement’s goal of keeping global warming under 2 degrees Celsius, and preferably under 1.5°C, but there are many challenges.

“Since 2010, rising demand for energy services in buildings – particularly electricity to power cooling equipment, appliances and connected devices – has been outpacing energy efficiency and decarbonisation gains,” the IEA said. “Very high temperatures and prolonged heatwaves set records in many countries, driving up demand for air-conditioning.”

The United Nations, in its latest climate assessment published in February, added that if greenhouse gas emissions remain high, all Asian regions studied in the report – Bangladesh, China, India, Indonesia, South Korea, Japan and Vietnam – will be affected by dangerously high heat and humidity levels, sea level rise, flooding and other physical climate risks.

As governments aim to meet ambitious climate goals, they will increasingly look to the building sector to reduce its impact on the environment.

By accelerating digitalisation and embracing the Internet of Things, artificial intelligence and other innovative digital technologies, we can achieve smarter, healthier and more sustainable buildings.

Chang Sau Sheong, chief executive, SP Digital

In Singapore, for instance, buildings make up over a third of the country’s electricity consumption. The city-state’s Building and Construction Authority (BCA) notes that the built environment plays a “major role” in helping to achieve the national sustainability agenda to tackle climate change and global warming.

This presents huge opportunities, and challenges, for landlords trying to drive efficiencies in commercial buildings. Technology is key in this effort, according to SP Digital, the digital arm of SP Group, a utilities group in Asia Pacific that focuses on low carbon, smart energy solutions.

“By accelerating digitalisation and embracing the Internet of Things, artificial intelligence and other innovative digital technologies, we can achieve smarter, healthier and more sustainable buildings,” said Chang Sau Sheong, chief executive of SP Digital.

Mindset shifts key to green buildings

Setting regulatory benchmarks and fiscal policies has helped to green buildings and boost efficiencies. Technologies and smart systems have also improved sustainability. But changing the behaviour of landlords and tenants could prove to be the biggest hurdle yet.

Dr Clayton Miller, assistant professor at the National University of Singapore (NUS) who leads its Building and Urban Data Science Lab, told Eco-Business that there are many underused green building technologies, including innovative cooling systems that tap on high temperature radiant, desiccant dehumidification and mixed-mode ventilation.

“There are too many decision-makers who want to play it safe and stick with conventional systems, because they are afraid that trying something different will bring problems,” he said.

Some property owners and landlords may be put off by the costs and difficulties of retrofitting older buildings for sustainability. For example, installing green technologies may require space that is scarce in buildings not designed for them.

“With the myriad of green technologies out there, one of the key challenges that building owners may face is simply how and where to start the retrofitting process,” added Associate Professor Kua Harn Wei, of the Department of the Built Environment, NUS School of Design and Environment.

A smart way to achieve sustainability

Tenants may be stymied by a lack of data too, noted Chang. “Most landlords and property owners provide monthly utility bills, which makes it challenging for tenants to know how and where to best focus their efficiency efforts, and track how they are faring,” according to Chang.

A typical office in Singapore expends most – 60 per cent – of its energy on cooling, according to BCA. Lighting takes up 15 per cent of consumption.

To give tenants and landlords more granular data to manage their energy and water use, SP Digital created Green Energy Tech (GET) TenantCare, a smart and automated tenant submetering solution. Tenants and landlords can get visibility of their utilities consumption in granularity of 30-minute intervals, unlocking more ways to save electricity and water. The platform not only increases operational efficiency, but can improve tenant engagement that will drive sustainability efforts, Chang said.

As a tenant, for instance, you can better understand how you use electricity, get alerted to unusual usage earlier, find out which of your equipment is using a lot of energy, whether through faults or inefficiency, and make changes to lower your energy consumption.

“If you’re a landlord, you can use our solution to automatically calculate your tenants’ energy use intensity, based on their units’ energy usage and gross floor area. You can identify which tenants are using more electricity than expected and engage with them to persuade them to adopt more energy-efficient equipment or habits,” Chang said.

Smart technologies have other advantages. With GET TenantCare’s automated meter readings, landlords do not have to deploy manpower to check on and read the meters. This also eliminates human errors in the readings.

Smart building management systems, connected to motion and other occupancy sensors and weather forecasting systems, can automatically adjust air-conditioning temperatures, switch off unneeded lights, and do more to save electricity and water while maintaining comfort for occupants.

Promoting greener behaviours

With insights from smart technologies leading to quick wins in energy and water savings, landlords and tenants may be more motivated to continue on their sustainability journey.

“If people have good experiences trying out sustainable behaviours, they are likely to repeat them and form green habits over time,” Dr Sonny Rosenthal, cluster director of smart and sustainable building technologies at the Energy Research Institute at Nanyang Technological University (NTU), told Eco-Business.

Other novel systems and ideas could enable tenants and landlords to work in tandem to slash the carbon footprint of the buildings they occupy.

SP Digital’s GET Engaged solution is a digital dashboard that provides updates on buildings’ electricity and water use, and the resulting carbon emissions. When displayed in lobbies and other public areas, the information could spur tenants to make more sustainable choices.

Equipping people with relevant skills is essential too. Last year, the Singapore government launched the Sustainability in Singapore programme, which trains people from organisations to be green ambassadors.

This includes teaching them how to design effective sustainability campaigns to persuade their colleagues and other occupants in their buildings to be more environmentally friendly.

BCA chief executive Kelvin Wong explained: “As a building user myself, we tend to think that staying in green buildings alone is sufficient. But this is not true. Practising sustainable behaviour within building premises is equally important to make the most of green buildings.”

“Hand in hand, both green buildings and sustainable user behaviour would translate to lower carbon emissions, with the added advantage of monetary savings,” he added.

The BCA has also created “green lease” toolkits to guide landlords and tenants in crafting mutually-agreed-upon, sustainability-related agreements for office and retail buildings. These would set out objectives for how the building is to be improved, managed and occupied to reduce its impact on the environment.

Greener buildings go beyond providing environmental and economic benefits, Chang noted. Greener buildings can also enhance occupants’ health and overall well-being.
